Rotating shaft mechanism for folding screen, folding screen assembly and foldable mobile terminal

Abstract

The invention discloses a rotating shaft mechanism for a folding screen, a folding screen assembly and a foldable mobile terminal. The rotating shaft mechanism comprises a left supporting arm and a right supporting arm which are symmetrically arranged, and the left supporting arm and the right supporting arm are fixed to a support. A left rotating shaft on the left support arm is connected with the left cam, a right rotating shaft on the right support arm is connected with the right cam, the left gear is in transmission connection with the left cam, the right gear is in transmission connectionwith the right cam, and at least one transmission gear is in transmission connection between the left gear and the right gear. The folding screen assembly comprises the rotating shaft mechanism, andthe foldable mobile terminal comprises the folding screen assembly or the rotating shaft mechanism. The folding screen of the foldable terminal can work more reliably and more smoothly, has the outstanding advantages of being simple in structure, easy to implement, low in cost, high in reliability, long in service life, wide in application range and the like, and can be widely applied to foldablemobile terminals.

Description

technical field [0001] The invention relates to the technical field of folding screen application design, more specifically, the invention relates to a hinge mechanism for a folding screen, a folding screen component and a foldable mobile terminal. Background technique [0002] With the continuous development of portable electronic devices, the display screens of mobile terminals such as mobile phones and tablet computers are becoming larger and larger. Although large screens can display more content for users at the same time, it also brings problems such as large electronic devices, Problems such as large space occupation and poor portability have restricted the development of large-screen portable electronic devices. In order to take into account the dual attributes of portability of various electronic devices and large screens, folding screen electronic products have emerged as the times require. [0003] 2019 is the first year of the launch of folding screen products. S...
